提出了一种梯度域色调映射算法，用于在低动态范围设备上显示高动态范围视频序列。该算法获得逐像素的运动矢量场，并将运动信息纳入泊松方程。然后，通过衰减大的空间梯度，所提出的算法可以产生高质量的色调映射的结果，没有闪烁的文物。仿真结果表明，该算法提供了一个更好的性能比基于帧的方法，其中每个帧独立处理。
A gradient domain tone mapping algorithm is proposed to display high dynamic range (HDR) video sequences in low dynamic range (LDR) devices in this work. The proposed algorithm obtains a pixelwise motion vector field and incorporates the motion information into the Poisson equation. Then, by attenuating large spatial gradients, the proposed algorithm can yield a high-quality tone-mapped result without flickering artifacts. Simulation results show that the proposed algorithm provides a better performance than the frame-based method, which processes each frame independently.
